Tubulars give a very nice ride, but are expensive to maintain. If you live in a flat prone area it is better to go tubeless because a flat with a tubular means your wheel is out of service for a couple of days (probably longer if you don’t do it yourself) and you have to replace an expensive tire.
I have not had a flat with a tubular in a long time, but I only use them for events and ride FWB tires. I ride out a bit to the left where there are less road derbies and carry a can of ‘Mariposa-Espresso’, which is basically fix-a-flat for bikes. If you use tubulars bring your AAA card and call it a day. AAA coverage includes picking you up if your bicycle breaks down.
